Automated gates on arrival for all nationalities, and thus eliminating stamps will be more difficult given the fact that different passports and visa types are granted different durations of stay.

I do too find, that outbound has longer wait times - at least, as BinSabai said, at fast track security queues can take forever and be the bottleneck, but immigration can too. Too many people have access..!

I still wish the AOT would limit fast track to F and J only….
